Factory Pump and Valve Assembly and Testing: Meeting Pump Curve Accuracy
February 14th, 2019In hydraulics equipment, factory-branded pump and valve assemblies are put under a big microscope. Well, the instruments aren’t optical microscopes, but they do analyze the performance of these key system components in great detail. Needless to say, the graphs produced by these analytical programs look quite outlandish, at least that’s how they appear to a […]
What are the Most Common Hydraulic System Accessories?
January 29th, 2019Along with the piston-driven pumps and actuators that form the main arteries of a hydraulic system, full-service hydraulic equipment manufacturers provide hundreds of different accessories. The system fittings refine certain performance-oriented qualities and generally improve the interface that forms between the components of a fluid circuit and its mechanical parts. Starting with filters and strainers, […]
What are NFPA Cylinders for Pumps?
January 15th, 2019Much like any other engineering discipline, hydraulics technology is rife with acronyms. The latest of which, NFPA cylinders, requires decoding. NFPA, strictly speaking, isn’t a descriptive acronym, it’s a shorthand way of referring to a regulatory body, one that’s known as the National Fluid Power Association. Equipped with many resources, one of this regulatory body’s […]
Positive Displacement Pumps: Important Things that You Should Know
December 13th, 2018Positive displacement pumps rule the hydraulics sector. Granted, an attempt by the sector to switch to non-positive displacement could be made, but the equipment based on this pump type would be unable to produce a positive internal seal. Yes, the gear would create a continuous flow, but that flow would vary as pressure changes took […]
Hydraulic Fluid Overheating: Causes and Remedies
December 10th, 2018A system malfunction is taking shape, and a hydraulic fluid overheating problem is causing major headaches. If the equipment owner is to avoid popping a painkiller, he needs to know what’s behind the heat generating riddle. On identifying the thermal energy source, only then can a remedy be implemented. Let’s start with a quick fluid […]
